[0021] See also Figures 1 to 3The utility model provides a technical solution: a photovoltaic film production and processing cooling device. The device mainly improves the loading and unloading processing method and cooling method during the cooling treatment of photovoltaic films in the prior art, with the purpose of improving the efficiency of loading and unloading operations, improving the uniformity of cooling and improving the cooling efficiency.

[0022] The device includes a base 1, a vertical plate 2 is fixedly provided on the top of the base 1, an exhaust pipe 3 is fixedly connected to the top of the vertical plate 2, the function of the exhaust pipe 3 is to discharge hot air outward, one end of the exhaust pipe 3 is fixedly connected to a cooling pipe 4, the cooling pipe 4 and the exhaust pipe 3 are coaxial, the outer peripheral wall of the cooling pipe 4 is provided with circumferentially uniformly distributed cold air inlets 41, the cold air inlets 41 are rectangular holes, at this time, when the airflow enters the cooling pipe 4 through the uniformly distributed cold air inlets 41, it will converge and then be discharged through the exhaust pipe 3, in this process, the flow rate of the airflow in the cooling pipe 4 is approximately equal everywhere.

[0023] Furthermore, one end of the cooling cylinder 4 facing away from the exhaust cylinder 3 is open, and a sealing door 5 is axially slidably provided at one end of the cooling cylinder 4 opposite to the opening of the cooling cylinder 4. The sealing door 5 is used to open and close the opening of the cooling cylinder 4, so that all the airflow in the cooling cylinder 4 is discharged from the exhaust cylinder 3. One side of the sealing door 5 is fixedly connected with a hollow film support plate 6 opposite to the middle of the inner cavity of the cooling cylinder 4. The hollow film support plate 6 is used to place the film material. Evenly distributed ventilation holes can be opened on the hollow film support plate 6, so that the airflow will be in a uniform cooling state when it flows through the inner cavity of the cooling cylinder 4 and then discharged from the exhaust cylinder 3, greatly improving the cooling efficiency.

[0024] Among them, a control assembly 7 for controlling the movement of the sealing door 5 is arranged on the base 1. When the sealing door 5 opens and closes the cooling cylinder 4, the photovoltaic film will move with the sealing door 5. This arrangement makes the loading and unloading operations of the photovoltaic film more convenient.

[0025] Specifically, the control assembly 7 includes a control motor 71 and a transmission screw 72. The control motor 71 is fixedly arranged on one side of the vertical plate 2 and its output shaft is fixedly connected to one end of the transmission screw 72. The control motor 71 provides driving force for the rotation of the transmission screw 72. The back of the sealing door 5 is fixedly connected to a connecting plate 51. One side of the connecting plate 51 is fixedly connected to a thread sleeve 511 sleeved on the transmission screw 72. When the transmission screw 72 rotates, the sealing door 5 is moved by the rotation action. One side of the vertical plate 2 is fixedly connected to a guide shaft 21 that penetrates the connecting plate 51 and is located below the transmission screw 72. In specific implementation, a limit sleeve sleeved on the outside of the guide shaft 21 can be welded on the connecting plate 51.

[0026] In this embodiment, a drainage tube 8 is fixedly sleeved on the outside of the cooling tube 4, and an annular sealing plate 81 fixedly sleeved on the outside of the cooling tube 4 is welded on the end of the drainage tube 8 facing away from the exhaust tube 3. The drainage tube 8 and the outer peripheral wall of the cooling tube 4 form an annular cavity 9 with an opening at one end, and the annular cavity 9 is connected to the inner cavity of the cooling tube 4 through the cold air inlet 41, that is, the annular cavity 9 plays a role in circulating and diverting the air flow, and an external air pipe can be used to supply air to the annular cavity 9, and the air flow fills the annular cavity 9, and part of the air flow will pass through the cold air inlet 41 from the outer periphery of the cooling tube 4 and evenly enter the cooling tube 4.

[0027] Furthermore, a rotating sleeve 101 is provided on the outside of the exhaust tube 3, and the outer peripheral wall of the rotating sleeve 101 is fixedly connected to an L-shaped suspension rod 1011, and the free end of the L-shaped suspension rod 1011 is rotatably connected to a rotating shaft 102 located in the annular cavity 9, one end of the rotating shaft 102 is fixedly connected to an impeller 103 opposite to the cold air inlet 41, and the other end of the rotating shaft 102 is fixedly connected to a bevel gear 1021, and the inner peripheral wall of the drainage tube 8 is fixedly connected to a bevel gear ring 82 meshing with the bevel gear 1021, so that when the rotating sleeve 101 rotates, it will drive the L-shaped suspension rod 1011 to revolve. At this time, under the action of the bevel gear ring 82, the rotating shaft 102 rotates at high speed, and the impeller 103 rotates at high speed to supply air to the cold air inlet 41, and the external airflow will enter through the open end of the annular cavity 9. This arrangement has the effect of avoiding the problem of air leakage to the outside through the opening of the annular cavity 9.

[0028] In this embodiment, a positioning hole 83 is penetrated through the wall of the drainage tube 8, which is close to the opening end and is evenly distributed circumferentially. A semiconductor refrigeration plate 104 is nested in the positioning hole 83. The cooling surface of the semiconductor refrigeration plate 104 faces the annular cavity 9, and the heat collecting surface faces outward. When the external airflow enters through the opening of the annular cavity 9, it will be cooled by the semiconductor refrigeration plate 104 to form lower cold air. After the lower cold air enters the cooling tube 4, the cooling efficiency can be further improved.

[0029] Working principle: before use, a transmission gear can be welded on the outside of the rotating sleeve 101, and then a driving motor can be installed on the vertical plate 2. The output shaft of the driving motor is installed with an active gear meshing with the transmission gear, thereby realizing the control of the rotation of the rotating sleeve 101. During use, when it is necessary to feed a number of photovoltaic thin film raw materials, the control motor 71 is started, and the transmission screw 72 rotates to drive the sealing door 5 to open. At this time, the hollow film support plate 6 is exposed, and then the above-mentioned raw materials are placed on the hollow film support plate 6, and then the transmission screw 72 is controlled to flip to send the hollow film support plate 6 into the cooling cylinder 4 to realize the loading operation, and vice versa, the unloading operation can be realized. During the cooling process, the rotating sleeve 101 is controlled to rotate, the L-shaped suspension rod 1011 revolves, and the impeller 103 rotates at a high speed. The external airflow is sucked into the annular cavity 9, and then enters the cooling cylinder 4 through the cold air inlet 41. At this time, the flow rate of the airflow around the raw materials is equal, and the airflow carries the heat on the raw materials and is discharged through the exhaust pipe 3, realizing efficient and uniform cooling of the photovoltaic thin film raw materials.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
